Hello everyone,

I run a 64bit system here and install flash plugins for firefox using nspluginwrapper. I get the movies but there is no sound.

Just check if the user is added to the audio group, try to check this as root user..hope other multimedia apps don't have the sound problem.

Everything else works without issues. Just the flashplayer doesn't have sound. :(

Make sure the 32-bit alsa-lib is installed.

alsa-lib.i386 1.0.6-5.RHEL4 installed

Can you playback sound using other 32 bit apps? e.g. using the 32 bit version of aplay?

I have aplay but don't know if it's 32bit or not.

What type of sound card do you have?

class: AUDIO bus: PCI detached: 0 driver: snd-via82xx desc: "VIA Technologies, Inc. VT8233/A/8235/8237 AC97 Audio Controller" vendorId: 1106 deviceId: 3059 subVendorId: 1043 subDeviceId: 812a pciType: 1 pcidom: 0 pcibus: 0 pcidev: 11 pcifn: 5

If you have a 64 bit distro installed, then aplay will be 64 bit - running:

Nope, but rpm -qa | grep alsa-util told me that I have the 64bit installed, which by the way does work fine.

should confirm this. To run the 32 bit version you will need to download the 32 bit (i386) alsa-utils RPM - but don't install it. Extract the 32 bit aplay binary by doing something like:

cd /tmp rpm2cpio alsa-utils-1.0.6-6.i386.rpm | cpio -idmv ./usr/bin/aplay

Roger, downloaded and extracted file.

However, as you are running CentOS4, you will need to make sure the snd_ioctl32 kernel module is loaded - it isn't by default i.e.

modprobe snd_ioctl32

Also completed.

Then test with the 32 bit aplay:

alsaunmute 0 /tmp/usr/bin/aplay /usr/share/system-config-soundcard/sound-sample.wav

No joy. it give the following output:

ALSA lib pcm_hw.c:549:(snd_pcm_hw_start) SNDRV_PCM_IOCTL_START failed: Broken pipe

and just sit there until I hit CTL-C

Same as mine ... however, I had lots of issues with 32 bit apps and sound on 64 bit CentOS4 (not necessarily this sound card) - in the end I 'upgraded' to the ALSA 1.0.15 kernel drivers, libs and utils - which works much better

Might have to walk down this same path Thnx for all your help and time.

The 32 bit kernel support for playback on 64 bit machines for older 2.6 kernels (including the RHEL4/CentOS4 kernel) didn't work properly until ALSA 1.0.15. RHEL4/CentOS4 is based on ALSA 1.0.6

As I said above, I've already been down this route - see:

Thnx again. I'm not a big fan of installing software that can't be installed via yum. If it becomes too big of a problem then I'mm walk this path. Thnx again fro all your help.
